In a contest that matches humans against some of the world's hottest chilli peppers, no one wins. Last week, restaurant in Edinburgh, Scotland, held a competition to eat the extra-hot Kismot Killer curry. Some of the competitive eaters were left writhing on the floor in agony, vomiting and fainting.

According to reports, two British Red Cross workers overseeing the event at the Kismot Indian restaurant in Edinburgh but became overwhelmed by the number of casualties and ambulances were called. Half of the 20 people who took part in the challenge dropped out after witnessing the first diners vomiting, collapsing, sweating and panting.

So what exactly are the health impacts of eating really hot chilli peppers? Can eating too much of the spicy stuff kill you?
